Biohealth® TH WSG is a water-soluble, organic fertilizer based on humic acid (potassium humate), seaweed and Trichoderma. The combination of humic acids, highly effective seaweed extract (Ascophyllum nodosum) and beneficial microorganisms (Trichoderma harzianum strains) supports strong and healthy plant growth. The beneficial microorganisms (Trichoderma harzianum) nourish on root exudates in the rhizosphere and increase plant resistance to pests, promoting the microbial population of the soil and rhizosphere. They mobilize inactive nutrients and make them available to plants. Humic acids and seaweed extract both stimulate root growth. Biohealth® TH WSG acts as an excellent soil conditioner.


  • Increases the resistance of the plant against abiotic stresses (drought, disease, high or low temperature and salt stress)
  • Increases the plant’s resistance against biotic stress 
  • Promotes root growth and helps regeneration of damaged roots
  • Increases nutrient availability from the soil
  • Stimulates root and plant growth and increases yield
  • Increases the buffering capacity of soils especially in unfavorable pH conditions
  • Enhances the germination of seeds and increases growth

“All Humintech humic substances based products are analysed according to the HPTA test method (ISO 19822:2018) to determine the content of humic and hydrophobic fulvic acids. Most suppliers are using the more simple “colorimetric” analysis method to determine the humic and fulvic acid contents, but experience shows that, due to its inaccuracy, this method indicates higher contents and is not suited to identify non humic substances such as lignosulphonates. In order to maintain the highest quality standard, Humintech has therefore decided to use the currently best analytical standard for the determination of humic and fulvic acids within the scope of quality control.”
